vprovide a side frame for railwaycars which can be economicallymade out sections of rolled steel, which weight .and composed of few parts, and

of commercial will be light in which will possess the necessary strength for the purposes to which it is applied. And a further object of the invention is to' mount and secure the journal boxes in the side frame in a novel manner without the use of bolts or similar fastening. means and where- 1b unnecessary rigidity is avoided and a .de sirableiflexibility provided.

- With these and other will hereinafter appear, 'Ihave illustrated the invention in two embodiments in thet ac- Y tional views onthe lines companying drawings, referring to ys'hieh- Figure 1 IS an elevation showing. my 1111- proved side frame; Figs. 2 and 3 are secspectively, of Fig. 1; Fig. 4 is a detail-secw tional view on the'line 4 4 of Fig. 1; Fig.

Fig. 7 is a transverse sectional View of the beam from whichthe compression and tension members are made in the embodiment of Fig. 6.

My improved side frame comprises a truss beam having a compression member and a tension member all in one integral part.

.In producing this truss'beam I may employ a rolled steel beam of commercial section or; I may roll a beam of suitable section.

' her of the truss beam.

In practice the beamis split longitudinally'betwe'en its endsand at or about midway between its top and bottom and while the beam is suitablvheld one of the split portions is stretched to providethe tension member of the truss beam and the other member is simultaneously compressed longitudinally to provide the compression mem- To enable this stretchingbperation theportion to be stretched or the'whole beam is first properly heated.

In order that the tension member may-be objects in view, as,

2-2 and 33, re-

stretching operation may prises corresponding and the tension member also comprises co rand said stretched and elongated the required amount without exceeding the safe limit of elongation of the metal or appreciably diminishing its strength, I prefer to shorten the compression member by upsetting or compress ing'it longitudinally at the same time that the stretching; action is performed upon the tension member. This compression may .be conveniently effected by applying pressure endwise of the beam and at the ends thereof while the tension member is being elongated and while the beam is suitably held in place. I have found that by employing this method I can elongate and expand the tension member of a seven foot/ channel beam to a drop of twenty-five inches, the compression memberbelng upset or shortened threemches during the operation. This upsetting 'and\shorten1ng of the compression memberfnot only enables the elongation of the tenslon member to provide for the desired drop or expansion thereof but it en-' larges the section of the compression member and thereby increases its strength and rigidity. The fabrication of my side frame in this-manner will develop any imperfections that may exist in the metal so that they will be detected before the frame is placed in service. a

In Figs. 1-5 a truss beam 8 is formed from a channel beam and the tension member 9 has been madeby stretching a portion similar to the portion 10 which forms the compression member.

The truss beam may be made'from a single rolled steelbeam of sufficient section or, for convenience of manufacture, from two beams as shown in Figs. 1-5, the other beam 8 having atension member 9 and a compression member 10. These two beams are riveted or otherwise suitably fastened to- .gether to form a single truss beam. 'The be performed on the two beams simultaneously or separately as will be found.mostconvenient. In this construction the compression member com- .parts of both beams responding parts of both beams, part-s operate conjointly to provide a single compression member and a single tension member. In making this form of truss beam I have found it conver ent to-empl'oy two channelbeams with their flat sides in 1uxtaposition; While the 0111.."1161 section many desirable advantages it will be understood that'I do not restrict myself to this or any other-particular shape but reserye the right to employ any shapeof rolled steel said members by frivets or are spot-welded.

thereto or otherwisesuitably secured in place.

A bar 12, preferably of T-section, is secnred'at its-ends to the truss beam, at the 'ends' thereof, and to the tension member, at the bottomthereof, by rivets or other suitable means, to form a binder to hold the joiirnal box-1n place. In Figs. 1-5 the bar 12 is secured between the ad acent ends of the beams S, 8, and between the two tension members 9, 9', the flanges of the bar bein" preferably removed for this purpose. The ar is bent or formed to accommodate and secure the journalboxes 13 in the frame and this is accomplished in a desirable manner without the use of bolts, or other fastening means, by providing the box with suitably disposed lugs to engage with the flanges of the beams of wh ch the frame is formed, as shown in Figs. 1, Q'and 5.. To t h1s end the journal box may be provided on its tpp t ie with lugs 14 to engage recesses 15in flanges of the beams 8, S, and with-lugs 16 on its bottom to engage recesses 17 in the flanges of the bar 12. The beams 8, 8', extend beyond the tension members thereof sutliciently'to form seats 18 for thejournal boxes which are held'in place by the bar 12 against the tension members. In assembling the. parts the boxesvare. arranged against the seats 18 and the bar is then fastened in place.- Th "lugs on the boxes engage the frame so matthe boxes are securely held inplace. This manner and means for securing the boxes in the side frame provides for a desirable ,de ree of flexibility and avoids an undesirable rigidity of parts. In eventof injury o the {ournal boxes or if it becomes necessary to "c iange them for any reasonthe bar can be removed from the other parts of the frame bysimply-cutting the rivets or releasing any other fastening means that may be employed.

A tie plate l9 of channel section is employed to'engage two side'frames of a truck and this plate .is cut away or recessed -at.19 to receive the tension member, Figs; 1 to 4. By reason of this engagement itwill not be necessary to fasten the tie plate to the side frames but I may rivet or otherwise secure it to the side frames if desired. 4

As hereinbefore mentioned a single beam may be employed instead bf the double suitable form are tween the two parts, of the as shown in the ends of the beam inwardly and pulled away I integrally connected with the beam 20 at the depressed central portion of the tension member and it is employed to. support the journal boxes 25 which are fastened thereto at 26 in any suitable manner and are also engaged with or fastened to the beam '20 as *hereinbefore described or in any other suitable manner. u

I My invention is capable of embodiment in side frames of various forms with such changes and- -alterations as may be desirable at or about its punctum-withthe beam from and 7 I have shownya single beam being of Lsect-ion.

illustration herein,

As hereinbefore indicated, I do'not wish to be understood asconfining the invention nor to the exact construe tion and arrangement and'adaptation .of 1

. parts shown and described, but I reserve the right to make any chan errand alterations thatfairly fall withintie' spirit and scope of the invention. 1

The compression mam rmaybe provided with a camber, iffles red', and the shape and e'onfigurationbL-the tension ,meinber may be varied as required to suit different conditions. In some instances it may be desirable to ,extend the tension member down further than is indicated in the draw;

ings to provide a dee r. opening in the side frame, and in suc cases I prefer to provide initially a beam stm eivliat longer than is require ,andcontract the compression member lengthwise, thereby increasing the drop of thetensionmember without unduly stretching the metal.
